Fujiwa Black Unglazed 1" x 1" Dot Mounted Porcelain Pool Tile

Product Overview

The Fujiwa Black Unglazed 1x1 (UNG-101C) is the gold standard for safety and high-contrast detailing in aquatic design. While white tiles create the "volume" of a pool, this unglazed black porcelain provides the critical "definition"—serving as the primary choice for lane lines, step markers, and "negative edge" details in both luxury residential and Olympic-spec commercial installations.

As part of the UNGLAZED collection, this tile prioritizes structural integrity and grip over decorative shimmer.

Fujiwa Unglazed Series | Black 1" x 1" Dot-Mounted Pool Tile

Achieve maximum safety and a bold, graphic aesthetic with the Fujiwa UNG-101C. This full-body porcelain tile is engineered to withstand the harshest environments, from high-traffic commercial splash pads to deep-water pool lanes.Because it is unglazed, the deep charcoal-black color is baked through the entire tile—it will never fade, peel, or wear away, even under constant UV exposure or heavy chemical treatment.

The Dot-Mounting system is a critical upgrade for pool professionals; unlike mesh, which can act as a "bond breaker," the dots allow for 100% mortar-to-tile contact, ensuring these tiles remain submerged for decades without popping.

Key Benefits for Commercial & Residential Use

• Superior Slip Resistance: The unglazed matte texture provides a high Coefficient of Friction (COF), making it the safest option for pool steps, tanning ledges, and zero-entry slopes.

• Safety Markers: Its deep black color provides the high-contrast visibility required by code for marking the edges of steps and deep-end transitions (Safety Nosing).

• Full-Body Construction: If a tile is chipped by a heavy pool vacuum or dropped equipment, the color underneath is the same as the surface, making damage nearly invisible.

• Architectural Flexibility: The 1x1 format easily conforms to the tight curves of "Cove" transitions and circular spa spillways.

Recommended Applications

Confirm the current manufacturer approval for the intended floor, wall, shower, pool, exterior, or commercial installation before specifying this product.

Installation & Handling Guidelines

• Mortar Choice: Use a Waterproof Polymer-Modified Thinset. While the tile is black, using a dark gray or black mortar can help prevent light-colored "bleed" in the grout joints.

• Grout Selection: * Black/Charcoal: Creates a sleek, monolithic look that is excellent at hiding algae or mineral buildup.

  • High Contrast: Pair with white unglazed tiles and white grout for a "checkered" or classic "art deco" pool bottom.

• Efflorescence & Scaling: On a black matte tile, white calcium scaling is more visible than on light tiles. Regular maintenance with a pool-safe descaler is recommended to keep the black looking deep and saturated.

• Layout: For safety "nosing" on steps, installers typically use 2 to 3 rows of these 1x1 tiles to create a clear visual boundary.

Care & Maintenance

Use a cleaner appropriate to the listed material and follow the manufacturer’s maintenance instructions. Test any cleaner or sealer on a spare piece first.

Frequently Asked Questions

Q: Will the black color get hot in the sun? A: If used on a dry deck or "coping" surface in direct 2026 summer sun, it will absorb more heat than white tile. However, when submerged or used as a waterline tile, the water keeps the porcelain at a comfortable temperature.

Q: Is it "stain-proof"? A: Yes. High-fired porcelain is impervious. While the surface is matte and has a slight tooth, it will not absorb oils or chemicals.

Q: Can this be used for "Lane Lines"? A: Absolutely. This is the industry-standard tile for racing lanes in competitive pools due to its durability and contrast against white or light-blue pool finishes.
